Hi, new here.
I'm going with (dare he say it?) GOKU, Yeah, I said it!
"But Goku can teleport across space even dimensions and the Kamehameha Wave and the Super Saiyin...."
Yeah and despite all that power, he has the brain of an 8-year-old as it was likely that his wife tricked him into having sex as he doesn't really care about anything, but fighting and training to fight some more. The only real reason he wins is that its always a p---ing contest between him and whatever villain is out to destroy the world where a deus ex machina comes along to make sure Goku wins. Goku even ADMITTED that he's a villain magnet at the end of the Cell Saga though he instantly comes back against Buu and in GT. Also Goku and his crew showed BALLS-OUT RIDICULOUS irresponsibility when he was given about 3 YEARS of advance warning to destroy the Androids BEFORE they could be activated and go on a killing spree, but NOOOOO!
"That's weak. I want a challenge. Let them be activated, kill people, almost kill my friends and family multiple times until I show up and pull something out my butt to save the day. We can ALWAYS use the Dragon Balls to wish everyone back!"
Everyone always compares him to a fight against Superman or Hulk, but honestly, BATMAN could beat him down by just outsmarting him. It's really not that hard as even the most "evil" of enemies never kicked him in the nads and/or interrupted his 5-minute long attacks and transformations and he'll kindly let any equally long finishing move gear up to hit him.
Goku's SUPPOSED to represent innocence, peace and determination, but honestly, he lives in a world of idiots where making money is apparently evil, no matter what the methods or intentions to do with said money, women are better nags than fighters and that the universe bends in his favor as the king idiot whether its an underestimating bad guy, a planet that's supposed to explode in minutes, but takes MONTHS to blow and of course, a new power/form to save the day.
Goku has all that power, but not only is he useless once the day's saved, but he RELIES on villains to justify his existence, otherwise he's just a bum that can only provide for his family by punching out giant fish. I'm not Superman's biggest fan, but at least when the day's over he actually HAS a life instead of being a fight junkie.
